Q20. A company operates a group of imaging satellites. The satellites stream data to one of the company's ground stations where processing creates about 5 GB of images per minute. This data is added to network- attached storage where 2 PB of data are already stored.The company runs a website that allows
Its customers to access and purchase the images over the Internet. This website is also running in the ground station. Usage analysis shows that customers are most likely to access images that have been captured in the last 24 hours. The company would like to migrate the image storage and distribution system to AWS to reduce costs and increase the number of customers that can be served. Which AWS architecture and migration strategy will meet these requirements?
A.Use multiple AWS Snowball appliances to migrate the existing imagery to Amazon S3.Create a 1-Gb AWS Direct Connect connection from the ground station to AWS and upload new data to Amazon S3 through the Direct Connect connection. Migrate the data distribution website to Amazon EC2 instances. By using Amazon S3 as an origin have this website serve the data through Amazon CloudFront by creating signed URLs. B.Create a 1-Gb Direct Connect connection from the ground station to AWS. Use the AWS Command Line Interface to copy the existing data and upload new data to Amazon S3 over the Direct Connect connection. Migrate the data distribution website to EC2 instances. By using Amazon S3 as an origin have this website serve the data through CloudFront by creating signed URLs. C.Use multiple Snowball appliances to migrate the existing images to Amazon S3. Upload new data by regularly using Snowball appliances to upload data from the network-attached storage. Migrate the data distribution website to EC2 instances. By using Amazon S3 as an origin have this website serve the data through CloudFront by creating signed URLs. D.Use multiple Snowball appliances to migrate the existing images to an Amazon EFS file system. Create a 1-Gb Direct Connect connection from the ground station to AWS and upload new data by mounting the EFS file system over the正确答案A
Direct Connect connection.Migrate the data distribution website to EC2 instances. By using webservers in EC2 that mount the EFS file system as the origin have this website serve the data through CloudFront by creating signed URLs.
